Comment (by ryandesign):

 Now that I have power again I can work on this again. Today I prioritized
 getting the buildbot system up and running again with everything except
 for the 10.15 worker. Maybe tomorrow I will work on getting 10.15 back
 online.

 I worked on transferring the earlier OS versions first because
 reinstalling earlier OS versions is more difficult. (Installer
 certificates expire, making OS and Xcode installation more tedious.) If
 the old SSD failed completely at some point during the recovery process, I
 wanted to have the difficult-to-restore OS versions done via cloning and
 leave the easy-to-restore OS versions to be done by Time Machine.
 Fortunately the old SSD hasn't failed completely yet and is still letting
 me read most data so hopefully I can do the 10.15 restore by cloning as
 well.

 I already had other VMs running 10.6 and 10.9 on network storage that I
 could boot to, run a contemporaneous version of CCC, and clone the disk
 from the failed SSD to the new one. I don't have an existing other VM for
 10.15. I plan to make one, then do the cloning. Cloning from a different
 OS version might work but I'm not sure so I'd rather play it safe, and it
 would be good to have that other 10.15 VM anyway for other reasons.
